How to calculate percentages in LESS CSS?
提问by HappyElephant
I would like to calculate the width of child-container (div etc) in percentages depending on the parent container with LESS CSS.
我想根据具有LESS CSS的父容器以百分比计算子容器（div 等）的宽度。
I am using the forumula by Ethan Marcotte: target / context = result.
我正在使用 Ethan Marcotte 的论坛：target / context = result。
Parent container: 620px
Child container: 140px
父容器：620px
子容器：140px
I am using this calculation:
我正在使用这个计算：
div.child-container {
width: (140/620)*100%;
}
However the output is:
但是输出是：
div.child-container {
width: 0.2258064516129;
}
I would like to move the decimal point two digits and add the %, like this:
我想将小数点移动两位并添加 %，如下所示：
div.child-container {
width: 22.58064516129%;
}
Any hints greatly appreciated.
任何提示都非常感谢。

According to the LESS CSS website, you need to change the order of your equation
根据LESS CSS 网站，您需要更改等式的顺序
The output is pretty much what you expect—LESS understands the difference between colors and units. If a unit is used in an operation, like in:
@var: 1px + 5;LESS will use that unit for the final output—
6pxin this case.
输出几乎是您所期望的——LESS 了解颜色和单位之间的差异。如果在操作中使用了一个单元，例如：
@var: 1px + 5;LESS 将使用该单位作为最终输出——
6px在这种情况下。
It should be:
它应该是：
width: 100%*(140/620);

Maybe the percentagefunction didn't exist when OP was asking but for future reference I add this answer.
也许percentage当 OP 询问时该功能不存在，但为了将来参考，我添加了这个答案。
div.child-container {
width: percentage(140/620);
}
